Haskell 安装可能损坏ghcjs的反射dom
我正在尝试使用Haskell 安装可能损坏ghcjs的反射dom,haskell,cabal,ghcjs,reflex,ghcjs-dom,Haskell,Cabal,Ghcjs,Reflex,Ghcjs Dom,我正在尝试使用cabal install安装reflection和reflection dom，我收到以下错误消息： $ cabal install reflex-dom ... cabal: The following packages are likely to be broken by the reinstalls: lens-4.15.1 ghcjs-0.2.0 free-4.12.4 kan-extensions-5.0.1 adjunctions-4.3 Use --force-
cabal install安装reflection
和reflection dom
，我收到以下错误消息：
$ cabal install reflex-dom
...
cabal: The following packages are likely to be broken by the reinstalls:
lens-4.15.1
ghcjs-0.2.0
free-4.12.4
kan-extensions-5.0.1
adjunctions-4.3
Use --force-reinstalls if you want to install anyway.
GitHub上的ghcjs镜头有没有办法安装一致的
和
？也许我需要更改.cabal
文件
这是终端的完整响应
和安装反射镜类似
$ cabal install reflex

据我所知，在linux环境中以一致的方式安装Reflect和Reflect dom（以及ghcjs）的最佳方法是遵循以下步骤
这个过程相当于克隆Reflect平台存储库并从该存储库中运行脚本“try reflect”。try reflection脚本启动一个shell，您可以从中运行ghcjs，它将完全访问reflection/reflection dom。此外壳环境独立于您以前在计算机上安装的内容，因此您不必担心弄乱镜头或任何其他已安装的阴谋包。大多数人使用堆栈来避免此类错误。自从我开始使用stack以来，我还没有遇到过重大的版本问题。也许是你的一个选择？你使用的是什么操作系统？@DaveCompton这是Ubuntu 16.04“Reflect platform/try Reflect”脚本已成为我默认的haskell工作环境，不仅适用于ghcjs，也适用于ghc。它既简单又可靠。
$ cabal install reflex
